Aspects Regarding Disturbances Produced by Fluorescent Tubes

This paper has a strong applicative character. There is presented a modern system for monitoring dynamic states, carried out with the help of a data acquisition board. It is insisted upon an original monitoring program conceived by the paper team. There are presented then two applications of using this system: a) (experimental) analysis of disturbances produced by a fluorescent tube; b) analysis of disturbances produced by a LED tube. A special attention is paid to the experimental aspects which emphasize the waveforms of the currents corresponding to some fluorescent tubes (in a few representative operation states). Finally, there are presented conclusions, which have been obtained by finalizing the research and the afferent bibliography.
